I have just snagged a reverse-key SV-1... and it arrived with the entire upper octave +1, from D up the E above, broken. I am taking it to a technician tonight, and he says that Korg can only get him the regular black keys, not the accidentals. Anyone know where I can buy reverse keys? These are weighted piano-style keys. I am hoping not to have to paint new ones, but that may be what it comes down to.
